Vital Corridor with Interregional Significance

I-580 is the primary east/west route connecting the Bay Area with Tri-Valley housing, Central Valley commerce, and access to the I-5 freeway to transport goods south to Los Angeles. It also serves as a significant regional and interregional commuter route. With connections to the broader interstate network, I-580 is a major gateway for goods movement into and out of the Bay Area’s five seaports, three commercial airports, and four rail freight terminals, as well as a primary route for eastbound travelers destined for the Sierra and Southern California.
The high volume of regional and interregional commuter and freight traffic in the corridor create ongoing operational challenges that will be addressed by the CSMP.
